MTN BAD SERVICE

On the 13 September 2019 I took my brand new Xperia iPhone in , as after only 4 months , it stopped working. To date , I still do not have a replacement phone. Communications have been disastrous, and fairly non existent. Despite even emailing the MTN customer care , I still have heard nothing. It is appalling. And to think I have supported them for over 20 years. This is unacceptable.
